run the upgradeConfig() utility on the machine that hosts
Administration Server. This utility upgrades the system configuration
of Access Manager to 11.1.2.3.0.

This step will upgrade the
OAM 11.1.2.0 configuration and policy store to OAM 11.1.2.3. The
upgradeConfig utility must complete successfully or Single Sign On
(SSO) to OAM-protected resources after upgrade will fail.

1) Shutdown
AdminServer + OAM Manage Server

2) The
upgradeConfig command needs to be run using the IPv4 stack. The
WL_HOME/common/bin/wlst.sh
file should be edited to add the java.net.preferIPv4Stack=true
property.3) $
